arance being had therein to the accompany- -i drawings.

xl-'ly invention relates to heel burnishing 'machines of the class in which the wax or.

burnishing agent is applied hot to the heel surfaces, by means of a revolving wheel.

` The obj'ect of my invention is to produce an eective and economical device for the .above purpose.

' It consists in certain novelfeatures of construction an'd arrangement, more particullarly of the'fwax pot or container, and the mechanism employed in the wax pot or container for transferring the hot liquid waxl in proper quantities from the pot to the pe- "ri'p ery of the burnishing wheel, all as here` na'ftbr more fully set forth in the following description of a machine embodying my invention and illustrated in the accompanying drawings forming a part hereof.

The novel features of my invention are pointed out and clearly defined in the claims at the close 'of the specification. f In the drawings, Figure 1 is an end elevation showing the essential portions of a machine embodying my invention. Fig. 2 is a detail partly in section showing a burlnishing wheel, the wax pot or container and the device for transferring the wax to the periphery of the burnishing wheel. Fig. 3 is a planview of the wax transferring and applying device. Fig. 4 is a detail in perspective of the wax applying segment. Figs. 5 and 6 are details showing a modified form of wax applying segment.

Having reference to the drawings, Ithe frame of the machine is shown at A, and is of common form and the ordinary construction. It is provided With a shaft B-which is driven in the Ausual and ordinary manner. On a free end of the shaft B the burnishing wheel is mounted as shown in Fig. 1. This Wheel may be of any Well known and ordinary form.

The burnishing agent is supplied to the wheel from a wax` pot or container lo cated directly beneath the burnishing wheelv and preferably of the shape shown in Figs.

i 1, 2 3nd 8. This container is mounted upon the Iframe of the machine by means of a lateral lug or extension 11, on the back side of the pot or container 10 as shown in Fig 1, which is provided with an adjusting slot 12 through which a bolt 13 passes to secure the extension 11 to the horizontal portion 14 of a bracket 15 which latter is also provided with an adjusting slot 1G through which two bolts 17 and 18 pass into the upright frame of the`machine. By this arrangement of bolts and slots the container is not only vertically adjustable, but is also laterally adjustnble, as will be clear. The container 10 has a slanting Hoor 19 and a nell 20. It is also provided with a transverse partition 21, having a hole 22 near the base thereof. This partition 21 forms a compartment rearwardly ther-eeft. e. to the left as shown in Figs. 1 and 2 in which a piece of solid wax may be placed which as it melts under the influence of the heat applied underneath the container from the burner 23, runsthrough the opening into the well 20 so that a proper supplylof wax is maintained in the well. The wam/transferring and applying mechanism comprisesa cross-bar 24 which is pivoted as shown in Figs.'2 and 3 between the sidewalls ofthe container fat vthe right hand end as shown in Fig. 3.v ./A sleeve 25 is secured centrally of theI cross-'bar and projects at right angles thereto as shown in Fig.

3. The sleeve 25 yreceivesl the cylindrical shank 26, see Fig. 2, of the yoke-'shaped support 27, said shank being retained in sind sleeve 25 by means of a set screw 28 whichv projects into an annular groove 29 in thesaid shank, thus permitting the shank to tilt (Er rock for the purposes, hereinafter set orth.

At the forward end of the yoke 2l' is pivoted a segment 30 by means of which the liquid wax is transferred from the well and applied to the periphery of the burnishing wheel. Outside of the wax pot or container is a projecting handle or lever 31, which is secured by means of a set screw 32 to the projecting trunnion 'of the cross-bar 24e, as will be clear from Figs. 1, 2 and 3. The segment 30 is normally in the position indicated by dotted lines as shown in Fig. ,1; The lower edge oef the segment is weighted, as will be clear from the, detailin Figs. 4 and 6, in whiohthe lower wall 33 is shownV Esci greatentbiclmess-than the uprevolving burnishiiig Wheel.

per wall 34. As the segment is pivoted in a yoke-shaped frame 27 the Weighted lower edge will drop down and the segment will assume the position shown in Fig. 1, which might be culled a Vertical position. .lt is prevented from swinging post the vertical by means of a stop pin 35 sct in the end thereof, which stop pin contacts with the arm of the .yoltc as will be clem' from Fig'. 2S. lVhcn the device is in its normal position shown in Fig. 1 the upper portion thereof is shove the level of the Wax, the lotter level. being indicated by dotted line 36, Fig. 1, and the full line 37, Fig. 2. The portion of this device which is Within the wax pot or container is only slightly heavier than the handle or tilting lever 3l, so that a very slight touch from the finger of the operator will serve to raise the segment 3G, forcing it into contact with the AS Sfgment is free to oscillete it will travel in contact with the periphery of the burnishing Wheel until it assumes the position shown in Fig. 2, at which time the segment con.-

tactswith the floor of the Wax pot and then it will again drop clear of the burnishing wheel and back into the Well 2O of the container.

The travel of the burnishing Wheel is so rapid that when the handle 3l is touched and the segment 30 is brought into Contact with the revolving wheel, it will remain in .Contact long enough to move the segment into the osition shown in Fig. 2. There will thus e applied to the periphery of the burnishing Wheel a transverse band of fresh wax. This wax is picked up by the burnishing wheel without causing any of the Wax to throw or spetter and one application of the wax by the segment is suthcient for e heel. yThere is therefore very great economy in. the use of the wax or burnishing agent. it is to be noted that in. the position shown in Fig. 2 one edge of the segment is in contact with the curved portion 38 of the door of the Wax pot. This portion of the floor is formed in this curved manner in order to accommodate this edge of the segment when the segment has moved over by contact with the revolving burnishing wheel. From the construction heretofore described in which the yoke 27 supporting the segment is provided with a circular shank 26 which is mounted in a sleeve 25 it wilP be clear that the yoke 27, and consequently the segment, maytilt transversely of the periphery of'the wheel. This is important in order that the Wax a plying segment may accommodate itself lly to the periphery of the wheel and come fully in contact therewith transversely thereof. When the burnishing wheel employed is convex in cross section, as shown, the wax applying segment should preferably be concaved, as shownin Figs.

he flat; that is, it should not he concaved asl shown in Figs. 3 and 4. out simply a straight line from end lo end, corresponding with the straight or flot periphery of the burnishing wheel. It is however frequently desired to change a hnrnishing wheel over for work of n different kind. It is not, however, feasible to remove the segment 30 when such a change is mode in the burnishing Wheel and substitute a new segment having a face corresponding with the face of the wheel with which it is to be used. This removal of the segment is not practicable, because it very hot hy reason of its being immersed normally in very hot Wax. void the necessity of removing the wax transferring segment, l make one-half of the periphery of the segment concaved and the remaining half fiat. See Figs. 5 and 6. By this means one and the same segment will cooperate 'with either a convex or a. fiat faced lburnishing Wheel. segment in Contact withthe wheel is such that the hnrnishing Wheel makes contact when the handle 3l is tilted with both the concave and the fist portions of the face of the segment, and the contact is suflicient whether the phlishing Wheel be convex or flat faced to supply the necessary quantitiy of wax to the periphery of the wheel. t

The roll 0f the 'i is therefore unnecessary to change the wax transferring segment if a change is made in the burnishing wheel. A

in the operation of my machine, the operetor standing in the usuel position, touches the tilting lever 31, which causes the transfer and application to the burnishing wheel of e proper amount of Wax for burnishmg one heel. vThe heel is applied'to the polishing wheel and is quickly coated and polv ished. He then presents the heel to the tion with e rotating burnishing 'wheel ofa pvoted segment having a" limited substantially arc-shwped wax applyngsurface, said artial re vo` y lution by contact with the burmshing wheel segment being rotatable foi' a and a plvoted su port under the control o the operator, said segment being mounted on said support where y it 1s movable into end out of contact with the burnishing wheel to make its partial revo lution.
